BAKING-OVEN.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed December l. 1904:. Serial No. 284.999.

To all whom it may concern:

Be it known that I, FRITZ KEMPTER, a subject of the King of Wurtemberg, residing at Stuttgart, Wiirtemberg, Germany, have invented new and useful Improvements in Baking-Ovens, of which the following is a specification.

The present invention relates to indirectly heated baking ovens with partitions arranged below the pipes supplying the top heat, said partitions being provided with openings.

The invention further consists in making said openings adjustable, so as to enable the ballper to reduce or increase the top heat at W1 In the accompanying drawings: Figure 1 shows an indirectly heated oven with a partition below the pipes, the partition having an opening near the door of the oven; Fig. 2 illustrates the manner in which the opening of the partition may be provided with an adjustable flap or damper; Fig. 3 shows a modification of the partition, the same consisting entirely of adjustable flaps or dampers; Figs. 4 and 5 show a modification of the par tition in which the same has the form of a curtain, and Figs. 6 and 7 show a modification of the partition in which the same is provided with a number of adjustable slides.

The letter a, indicates the furnace; b, the hearth of the oven, and c, the water tubes that are heated from the furnace andare located within a top chamber arranged above the baking chamber. Below the upper tubes 0, a partition d, is arranged with an opening e, near the door f, of the hearth. The opening 6, may be controlled by a pivoted flap or damper 9, (Fig. 2), provided with lever h, which is connected to rod "5, having handle 76.

Fig. 3 illustrates a modification of the invention. The partition here consists entirely of adjustable flaps g. The flaps are preferably arranged in several groups, the levers h, of each group being connected by a common coupling rod Z, m, or n, with handles 0, p, and q, respectively. It will be understood that the number of the groups is not restricted to three, as shown, but that any suitable number of groups may be emplplyed, or all the flaps be connected to each ot er. I

In Figs. 4 and 5, a curtain r, is shown, which is suspended by rings 8, s, on rods t, and adapted to be adjusted to any suitable length by means of a handle it.

Figs. 6 and 7, show another modification of the invention, in which the flaps are replaced by slides 12. There is a rigid partition d, provided with openings 6, which may be opened to any suitable degree by means of the handles w, w, connected to the slides v, 1 Some of the slides may be connected by rods 00, and moved integrally by one handle w, as shown in the right part of Fig. 7. The slides are movable between angle-bars 'y, and 2, which latter also carry the partition (i, (Fig. 6). Any other suitable arrangement may be used for holding the slides and partition.

The common object of all the modifications shown is to enable the baker to reduce or increase the top heat at will, and further to enablehim to supplymore or less top heat to some part of the baking hearth.

What I claim is:

1. A bakers oven provided with a baking chamber, a superposed top chamber, a furnace, heating tubes in the top chamber communicating with the furnace, a partition having an opening between baking chamber and top chamber, and means for controlling the flow of heat through said opening, substantially as specified.

2. A bakers oven provided with a baking chamber, a door controlling the same, a top chamber above the baking chamber, a furnace, heating tubes in the top chamber communicating with the furnace, a partition between baking chamber and top chamber, said partition having -an opening near the door of the baking chamber, and means for controlling the flow of heat through said opening, substantially as specified.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

FRITZ KEMPTER.
